Hi Úna,
we’ll meet rockets more extensively in Module 5, but you have described perfectly how inquiry learning can be used with rockets as the activity.
The launch of a rocket makes a perfect prompt, and then the design and make acts as the investigation section. As the children play with their rockets they can make changes to improve the rocket’s flight, based on what they notice about the rocket. This gives immediate feedback.
We make a lot of rockets with children, and the excitement they share when they get the rocket to launch is very real. We find the foam rocket is good for 1st class (at the end of the year) if you have some extra hands to help with the duct tape. 2nd and up are fine with it, and 3rd class children usually have the record for how fast they can make one (an entire class in about 23 minutes).
